UK Nutrition Labels & HFSS Ad Bans: What Changes in 2026
The United Kingdom's restrictions on the advertising and promotion of products high in fat, salt, and sugar (HFSS) have been phased in over several years, and 2026 marks the year when the full suite of measures is in effect. These regulations fundamentally change how food and supplement businesses can market their products across television, online platforms, and in retail environments.
For food businesses, understanding whether your products are classified as HFSS — and what that classification means for your marketing, labelling, and retail strategy — is now essential for compliance and commercial viability.
The HFSS Restrictions Timeline
The UK government introduced HFSS restrictions in stages to give businesses time to adapt:
October 2022: In-Store Placement Restrictions
The Food (Promotion and Placement) (England) Regulations 2021 restricted where HFSS products can be placed in stores with 50 or more employees. HFSS products cannot be displayed at store entrances, aisle ends, or checkout areas. This applies to physical retail environments including supermarkets, convenience stores, and specialist food shops.
January 2025: Volume Promotions Ban
Multi-buy promotions such as "buy one get one free," "three for two," and similar volume-based offers on HFSS products were banned. This applies both in-store and online. Price reductions on individual items are still permitted, but volume incentives are not.
January 2026: TV Watershed and Online Advertising Ban
The most significant restriction came into force in January 2026. HFSS products are now banned from:
- Television advertising before the 9pm watershed — no HFSS product advertising is permitted on any UK television channel before 9pm
- Paid-for online advertising — a complete ban on paid HFSS advertising across social media platforms, search engines, video sharing platforms, and display advertising networks
This online ban is particularly broad. It covers paid search results, sponsored social media posts, display banners, influencer partnerships (where payment is involved), and video pre-roll advertising. Organic social media posts and a brand's own website content are not covered by the ban, but they must still comply with ASA CAP Code rules on food and supplement advertising.
What Makes a Product HFSS?
A product is classified as HFSS if it scores 4 or more points for food (or 1 or more for drinks) under the UK Nutrient Profile Model (NPM). The NPM calculates a score based on:
A Points (negative — nutrients to limit):
- Energy (kJ)
- Saturated fat (g)
- Total sugars (g)
- Sodium (mg)
C Points (positive — nutrients to encourage):
- Fruit, vegetables, and nuts percentage
- Fibre (g)
- Protein (g)
The final score is calculated as: Total A Points minus Total C Points. If the result is 4 or more for food, the product is HFSS.
Our food labeling software [blocked] includes an NPM calculator that automatically determines whether your products are classified as HFSS, helping you understand the marketing implications before you launch.
For a detailed guide on how to calculate NPM scores, see our article on The UK Nutrient Profile Model Scoring Guide [blocked].
Which Product Categories Are Affected?
The HFSS restrictions apply to specific product categories defined in Schedule 1 of the regulations:
| Category | Examples | Commonly HFSS? |
|---|---|---|
| Soft drinks | Energy drinks, flavoured waters | Often |
| Savoury snacks | Crisps, nuts, popcorn | Usually |
| Confectionery | Chocolate, sweets, cereal bars | Usually |
| Ice cream | All frozen desserts | Usually |
| Cakes and biscuits | All baked sweet goods | Usually |
| Morning goods | Croissants, pastries | Often |
| Puddings and desserts | Yoghurts, mousses | Sometimes |
| Pizza | All pizza products | Usually |
| Ready meals | Pre-prepared meals | Sometimes |
| Breakfast cereals | All cereals | Sometimes |
Food Supplements and HFSS
Food supplements are not explicitly listed in Schedule 1 and are generally not subject to the HFSS advertising restrictions. However, products that blur the line between food supplements and food products — such as protein bars marketed as supplements, gummy vitamins with high sugar content, or meal replacement shakes — may fall within scope depending on how they are categorised and marketed.
If your product could be classified as either a food supplement or a food product, it is essential to ensure the correct categorisation. Our Label Compliance Checker [blocked] can help you determine the appropriate classification.
Impact on Digital Marketing
The online advertising ban has significant implications for food businesses that rely on digital marketing:
- Paid search — Google Ads, Bing Ads, and other search advertising for HFSS products is prohibited
- Social media advertising — paid posts on Facebook, Instagram, TikTok, X (Twitter), and LinkedIn for HFSS products are banned
- Display advertising — banner ads, native advertising, and programmatic display for HFSS products are prohibited
- Influencer marketing — paid influencer partnerships promoting HFSS products are covered by the ban
- Video advertising — pre-roll, mid-roll, and post-roll video ads for HFSS products on YouTube and other platforms are banned
Organic content, email marketing to existing customers, and a brand's own website are not covered. However, all marketing communications must still comply with the ASA CAP Code and must not make misleading claims.
We are developing a Digital & Marketing Compliance Checker [blocked] that will scan your website, social media posts, and marketing materials against all UK advertising regulations, including HFSS restrictions.
How to Reformulate to Avoid HFSS Classification
If your product scores 4 or more on the NPM, you may be able to reformulate to bring the score below the threshold:
- Reduce sugar content — replace sugars with permitted sweeteners or reduce overall sweetness
- Reduce sodium — use alternative flavouring methods or reduce salt content
- Reduce saturated fat — switch to unsaturated fat sources where possible
- Increase fibre — adding fibre increases C points, which reduces the overall score
- Increase fruit, vegetable, and nut content — higher FVN percentage increases C points
Our Formula Builder [blocked] tool can model different formulations and instantly calculate the NPM score, allowing you to optimise your recipe before committing to production.

Enforcement and Penalties
The Office of Communications (Ofcom) enforces the TV advertising restrictions, while the Advertising Standards Authority (ASA) monitors online and print advertising compliance. The Competition and Markets Authority (CMA) oversees in-store placement and promotions compliance.
Penalties for non-compliance can include:
- Removal of advertising — the ASA can require immediate removal of non-compliant ads
- Adverse publicity — ASA rulings are published and can damage brand reputation
- Referral to Trading Standards — for persistent or serious breaches
- Financial penalties — Ofcom can impose fines for TV advertising breaches
Frequently Asked Questions
Are food supplements affected by HFSS advertising restrictions?
Food supplements are generally not listed in the HFSS product categories. However, products that could be classified as either supplements or food products (such as protein bars, gummy vitamins, or meal replacement shakes) may fall within scope. Correct product categorisation is essential.
Can I still advertise HFSS products on my own website?
Yes. The online advertising ban covers paid-for advertising on third-party platforms. Your own website, organic social media posts, and email marketing to existing customers are not covered by the ban, though they must still comply with ASA CAP Code rules.
How do I calculate whether my product is HFSS?
Use the UK Nutrient Profile Model (NPM). Calculate A points for energy, saturated fat, sugars, and sodium, then subtract C points for fruit/veg/nuts percentage, fibre, and protein. A score of 4 or more for food means the product is HFSS.
What is the penalty for advertising an HFSS product online?
The ASA can require immediate removal of the advertisement, publish an adverse ruling, and refer persistent offenders to Trading Standards or Ofcom for further action including financial penalties.
